Overloading some nodes in a complex radial distribution network can lead to serious voltage deviation problems. Configuring a large-capacity dynamic voltage restorer is an effective measure to solve the node voltage offset problem. This paper proposes an optimization method for configuring highcapacity dynamic voltage restorers based on sensitivity analysis, which can quickly and reasonably select the installation location and capacity of high-capacity dynamic voltage restorers in the distribution network. It can quickly solve the installation location and capacity of large-capacity dynamic voltage restorers. Considering the vertical and horizontal structure of the radial distribution network, a governance model that focuses on vertical governance is proposed and supplemented by horizontal governance. First, the sensitivity of the large-capacity dynamic voltage restorer is calculated for all nodes using sensitivity analysis methods. In this way, the installation position of the large-capacity dynamic voltage restorer is obtained. Second, the sum of the absolute values of the voltage offset at the nodes of the radial distribution network is taken as the objective function. Establish a large-capacity dynamic voltage restorer capacity-optimized model. Finally, the optimization model is solved by improving the particle swarm algorithm. A case study was conducted on a 41-node radial system. The simulation results verify the rationality and effectiveness of the proposed scheme.

An all-dielectric phase gradient metasurface is proposed, which consists of a periodic array of elliptical silicon nanopillars with a phase difference of π on a quartz substrate. The polarization and transmission characteristics of the unit half-wave plate structure are comprehensively studied, and the simulation results show that its transmission efficiency in multiple communication frequency bands can reach 98%, and the polarization conversion efficiency can reach 90% ∼ 99%. Furthermore, we arrange the half-wave plates as a periodic integrated supercell array, which realizes the polarization conversion and spatial separation of the beams. he proposed all-dielectric metasurface offers a strategy for creating compact, integrated and high-performance plasmonic multifunctional devices. © 2022 IEEE.

As a new type of regulation resource with two-way regulation function, energy storage is increasingly involved in automatic generation control and has become the key to the future frequency modulation (FM) auxiliary service market. In this paper, we propose an optimization strategy for market clearing of electric energy and frequency modulation based on the combination of thermal storage, which uses the security constrained unit combination (SCUC) model to determine the unit output plan and storage charging and discharging plan, and is based on the security constrained economic dispatch (SCED) model, with the objective of minimizing the total cost of the electric power system for market clearing. The system frequency stability is maintained by adjusting the output of generating units in order to respond quickly to changes in the system frequency. In this paper, we study the issues related to the participation of solo energy storage in the electric energy and frequency modulation market, including the market demand for frequency modulation auxiliary services, resource allocation strategy, security constrained unit combination (SCUC), and security constrained economic dispatch (SCED), etc., and utilize the data of frequency modulation auxiliary services provided by each unit in the power system to calculate the frequency modulation mileage and the capacity clearing price of each unit, as well as to construct the arithmetic example and evaluate its feasibility and economic benefits.

The integration of wind power into the power system is becoming increasingly evident as the installation of wind power continues to expand. Due to the inherent volatility and uncertain nature of renewable energy, accommodating large-scale wind power is a challenge, and the risks for safe and stable operation of the power system are also increasing, such as system oscillation caused by weak inertia. Considering that there are usually dozens or even hundreds of wind turbines in a wind farm, which leads to the high order wind farm models in the detailed modeling with complex coupling between wind turbines, an reasonable and effective equivalent model of wind farms is the basis for studying the oscillation mechanism, characteristics of power system. Therefore, this article proposes a high adaptability equivalent algorithm for wind farm based on track sensitivity and parameter identification. The simulation results show that the equivalence way proposed in this paper reflect the dynamic characteristics accurately of doubly fed wind farm grid points.

Accurately estimating the state of charge (SOC) of lithium-ion is very important to improving the dynamic performance and energy utilization efficiency. In order to reduce the influence of model parameters and system coloured noise on SOC estimation accuracy, this paper proposes the SOC estimation based on online identification. Based on the mixed simplified electrochemical model, the forgetting factor recursive least squares (FFRLS) method was used to identify the parameters online, and the SOC estimation was carried out in combination with Unscented Kalman Filter (UKF). Finally, the accuracy and feasibility of the method are verified by Federal Urban Driving Schedule (FUDS), the online identification and SOC estimation are carried out. The experimental results show that the SOC estimation of online parameter identification is more accurate, the system stability is faster and the error is smaller. © The Authors, published by EDP Sciences, 2020.

As the penetration of renewable energy increases, the mechanical inertia of the power system decreases, weakening the system’s ability to withstand disturbances, particularly during large frequency events. Smart buildings on the demand side show promise as candidates for providing frequency regulation. This paper presents a fast frequency response test for smart buildings. A series of tests, including frequency step tests, frequency ramp tests, and hybrid tests, were conducted to assess the fast frequency response performance of smart buildings. The results indicate that the building has regulation capabilities comparable to traditional generator units in primary frequency control and demonstrates strong potential for fast frequency response. These findings are now being used to guide the development of standards for demand-side adjustable resources participating in fast frequency response.

The proportion of photovoltaic power generation in the global energy structure is increasing year by year. Because of its volatility and periodicity, grid-connected photovoltaic challenges the safe and stable operation of power grid. One of the ways to solve this problem is data mining. Data mining needs high-quality data support, and data cleaning is one of the important means to improve data quality. Aiming at the problem of poor quality of original PV data, this paper analyzes two typical outliers of PV data and proposes a PV output data cleaning method based on Density-Based Spatial Clustering of Applications with Noise (DBSCAN) clustering algorithm, quartile algorithm and Pearson correlation coefficient interpolation method. Comparison of DBSCAN clustering algorithm combined with the quartile method of outlier identification with the quartile method alone outlier identification, the effectiveness of the method proposed in this paper is verified. Then using the method proposed in this paper for outlier identification based on Pearson correlation coefficient interpolation and cubic spline interpolation to verify the data filling effect, the results show that Pearson correlation coefficient interpolation is superior to cubic spline interpolation. Finally, two sets of data with different data cleaning methods are substituted into the Long short-term memory (LSTM) Model to verify accuracy of the cleaning method proposed in this paper.

Accurate identification and position of transmission lines is critical for robots to safely and effectively perform distribution network operations. However, such tasks are often challenged by complex lighting conditions, where depth information can be easily lost. Transmission lines have limited texture features and reflective surfaces, making it difficult to match image feature points. To address these challenges, this paper proposes a visual perception system for weak texture targets under complex lighting, based on an “eye-on-hand” configuration and a depth complementation algorithm. Furthermore, a high-precision identification and localization method for transmission line grasping points is developed, utilizing the fusion of binocular visual color maps and depth maps. The proposed method has been shown to effectively solve the problem of identifying and localizing the grasping points of transmission lines under complex lighting conditions. Experiments demonstrated that the method can improve the localization accuracy to within $\pm 4\text{mm}$ , outperforming other algorithms. The method is characterized as simple and efficient, and it enhances the environmental adaptability of distribution network robots.
